Sports shoe brush/scraper mount for attachment to the bumper of a cart

ABSTRACT

A brush/scrapper device cleans dirt and debris from the soles of outdoor sports shoes, such as the cleats of golf or other such shoes. The device is a single piece frame having a body portion to which a brush is mountable and an appendage portion for engaging a bumper. The frame being a single piece bent to form the body and appendage portions and is removably mountable on the bumper of a vehicle like a golf cart without modification of the vehicle.

BACKGROUND OF THE INVENTION

Various types of sports shoes are intended for wear and use on natural ground, turf and similar surfaces. Such sport shoes often have cleats, spikes or other features on the bottom surface of the soles to increase traction. These traction features can be subject to the accumulation of mud, soil, turf and the like in the course of being worn. Golfing shoes are an example of such sport shoes, and have cleats on the bottom sole which are subject to the buildup of dirt and other muck between the cleats. To remove such buildup, a golfer must carry a cleat cleaning device with them, such as a brush or a scrapper. Therefore, it is desirable in the field to have available an alternative cleat cleaning device to spare the golfer from having to carry one around that is soiled from use. The field has been motivated to provide alternatives to having to personally carry a cleat cleaning tool.

An example of an alternative cleat cleaning tool is disclosed in Woodward, U.S. Pat. No. 6,363,567. Woodward discloses a vehicle mounted golf shoe brush that is extendable from and retractable under the rear bumper of a vehicle. The mount element of the Woodward device is relatively complex having multiple component parts, some of which are required to move in relationship to each other. Other examples of shoe cleaning brush devices attachable to a golf cart are disclosed in U.S. Pat. Nos. 6,032,316 and 5,437,075 to Peake. The Peake devices both include hinge mechanisms for changing the positioning of the brush elements of the device, and are made of multiple separate components. A further example is the golf shoe cleaning device of U.S. Pat. No. D318,826 to Parchment, which discloses a brush and hinge assembly allowing the brush feature to be enclosed in a housing when not in use. There are other types of golf shoe cleaning devices known in the literature. See U.S. Pat. Nos. 3,142,853 and D356,892 to Hensley and to Ricci, respectively. These devices are mountable to round stock such as may be found on a pole.

Although each of the above shoe cleaning devices mountable on a vehicle may be useful for their intended purposes, it is clear that the field finds useful such devices mountable on a vehicle such as a golf cart. Also, because these devices may be exposed to weather as well as the accumulation of soil and other debris or muck, any moving parts may become fouled and/or corroded. It would be beneficial in the field to have an alternative shoe cleaning device that is attachable to a golf cart, yet does not have moving parts that may be subject to binding up due to fouling or corrosion. In addition to simplicity, it would be beneficial to have such a shoe cleaning device providing for its easy mounting and removal from the vehicle, and for which the work face (brush, scraper or the like) could be separately and easily replaced.

SUMMARY OF THE INVENTION

The present invention is a device useful for cleaning dirt and other debris from the bottom sole of a outdoor use sports shoe. Sport shoes for “outdoor use” often have cleats, spikes or other features on the bottom surface of the soles to increase traction. These traction features can be subject to the accumulation of mud, soil, turf and the like in the course of being worn. The present invention is useful for cleaning such material from the features on the bottom sole of such sport shoes. A specific example of such features and shoes are the cleats on the bottom sole of golf shoes. Examples of other types of such sport shoes include baseball spikes, football and soccer cleats.

In use, the present invention is mounted on the bumper of a vehicle such as a golf cart. The bottom sole of a golf shoe is cleaned by the wearer drawing the sole of the shoe to be cleaned across the work face of a brush or scraper mounted on the present device. The present shoe cleaning device mount can be practiced with a standard golf cart as are typically in the field.

The present shoe cleaning device mount comprises a single piece frame member having two major potions: a body portion and an appendage portion. A cleaning unit is mounted to the body portion of the single piece (unitary) frame member. The body portion has a generally triangular cross-section with a first side of the triangle forming the back of the body portion, a second side of the triangle forming the bottom of the body portion and the third side forming the front of the body portion. Further, the front side of the body portion has mounting means for attaching a cleaning unit to the body portion of the frame. The appendage portion of the frame/mount is integral with the body portion, and extends from the top of the frame (where the back side and the front side of the body join), and is formed to receive the bumper between itself and the frame back.

It is intended that the present sports shoe brush/scraper mount be simply and easily attachable and removably to the bumper of a vehicle, such as a golf cart. That is, by hand or and without modification of the vehicle. A clamping fastener, such as a set screw, may be provided to pass through the appendage portion and/or the back side of the body portion to secure the frame member to the bumper to accomplish the intended ease of attachment and removablity. Additionally, it is an intended option that the cleaning unit be replaced if desired.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, the details of preferred embodiments of the present invention are graphically and schematically illustrated. Like elements in the drawings are represented by like numbers, and any similar elements are represented by like numbers with a different lower case letter suffix.

As exemplified in FIGS. 1A and 1B, the present invention is a sports shoe cleaning device 10 for the removal of dirt and other debris or muck from the bottom sole of an outdoor use sports shoe. The present sports shoe cleaning device 10 comprises a unitary frame member 14 having a body portion 40 and an appendage portion 60. A cleaning unit 20 is mounted to the body portion 40 of the frame member 14. Typically, the present shoe cleaning device is removably mounted on the bumper of a vehicle like a golf cart. The device is useful for removing dirt and other buildup from the traction features (not shown) on the bottom sole of an outdoor use sports shoe. A example of such traction features are the cleats on the bottom sole of golf shoes.

As illustrated in FIGS. 2A and 2B, the unitary frame member 14 is constructed as a single piece which integrally incorporates both the body portion 40 and the appendage portion 60 of the device 10. The unitary frame member 14 can be constructed of any of a variety of materials selectable to one of ordinary skill in the art. In a preferred embodiment, the frame member 14 was constructed of a single piece of sheet metal. However, the ordinary skilled artisan knows of other materials suitable for practicing the frame member 14, such as metal flat stock, plastic flat stock or a combination thereof. It is intended that any flat stock type material utilized for the single integrated piece be bendable to form the body 40 and appendage 60 portions of the unitary frame member 14. Alternatively, the unitary frame member can be molded or cast, for example as a single, injection-molded plastic piece.

The starting dimensions of a flat stock or bendable single piece frame member 14 are selectable by the ordinary skilled artisan. In a preferred embodiment the frame member 14 started as a single piece of aluminum sheet metal and had a length L, a width W and a thickness T of: 14 inches, 5 inches and {fraction (3/32)} inch, respectively. The side tabs 16 each had a width F of 1.5 inches and were split to a depth D of 4 inches leaving a center tab 18 which had a width f of 2 inches. As illustrated in FIGS. 2A and 2B, the body 40 and appendage 60 portions of the present sports and outdoor shoe scraper device 10 are formed by appropriately bending the single piece frame member 14 into the proper configuration. In the embodiment shown, the body back 42 was about 3.5 inches, the body bottom 46 was about 4.5 inches. When the single piece frame member 14 starts as a piece of flat plastic, it can be advantageous to form a groove (not shown) in the plastic along the line of the intended bend to facilitate bending the plastic piece to the desired configuration. Also, if desirable, either the side tabs 16 or the center tab 18 may be further shortened as the ordinary skilled artisan finds appropriate in practicing the present invention. In the embodiment shown, the side tabs 16 were shortened by 2 inches relative to the center tab 18.

The body portion 40 of the preferred outdoor/sport shoe cleaning device 10 had a substantially triangular cross-section with a first side of the triangle forming a back side 42 of the body portion 40, a second side of the triangle forming a front side 44 of the body portion 40 and a third side of the triangle forming a bottom side 46 of the body portion 40. Note the feature of this embodiment wherein the front side 44 of the body portion 40 is discontinuous and comprises one or more front-upper tabs 44 a and one or more front lower tabs 44 b. The front-upper tabs 44 a and front lower tabs 44 b had mount means 50 disposed on them for mounting a cleaning unit 20 to the body portion 40 of the frame member 14. In the embodiment illustrated, the mount means 50 were through holes for passing a fastener 52, and the cleaning unit 20 was mounted to the front side 44 of the body portion 40 of the frame member 14 using a threaded fastener 52, i.e., a combination nut and screw assembly. However, other means are known to and practicable in the present invention by the ordinary skilled artisan, such as self-tapping fasteners, pop-rivets, clamping means, clip means and adhesive means. In the embodiment shown in FIG. 1A, the cleaning unit 20 of the sport shoe cleaning device 10 was a stiff bristled brush. Such brushes appropriate for practice in the present device 10 are known in the art and are commercially available. Alternatively, the cleaning unit 20 can be a scrapper unit such as a boot scrapper, or a combination brush/scrapper unit.

In the embodiment illustrated in FIGS. 1A & 1B and FIG. 3, the body portion 40 had a substantially right-triangular cross-section with the height of the right triangle forming the body back 42, the hypotenuse forming the body front 44 and the base of the triangle forming the body bottom 46 of the body portion of the frame member 14. However, it is not a requirement of the present device 10 that the body portion 40 of the frame member 14 have a right triangular cross section. (For alternative examples, see FIGS. 4 a to 7). In fact, it is intended in the present invention that a frame member 14 made of a relatively bendable material, such as aluminum sheet metal or certain kinds plastic stock, will have some flexibility to allow ready adjustment to permit at least slightly different size cleaning units 20 to be mountable on the frame member 14. It is the feature of front side 42 of the body portion being discontinuous and in two parts 42 a & 42 b that enables this flexibility.

In the preferred embodiment exemplified in FIGS. 1A and 1B, side tabs 16 were folded forward to form the front tabs 44 a of the front side 44 of the body portion 40, and the center tab 18 was used to form the appendage portion 60. Alternatively, as illustrated in FIG. 3, the center tab 18 can be folded forward to form the front tab 44 a of the front side 44 of the body portion 40, and the side tabs 16 are then used to form the appendage portion 60.

The appendage portion 60 of sport shoe cleaning device 10 is used to attach or interface the device 10 the bumper 80 (see FIG. 3) of a vehicle. In the preferred embodiments illustrated, the vehicle was a golf cart. In the embodiment exemplified in FIGS. 1A and 1B, the appendage portion 60 of the unitary frame member 14 extended away from the back side 42 of the body portion 40 proximate the front side 44 of the body portion 40. In this embodiment, the appendage portion 60 was adapted to hold the bumper 80 against the back side 42 of the body portion 40. This was accomplished by bending the center tab 18 of the frame member 14 to make a downward extending leg 62. The downward extending leg 62 of the appendage portion 60 had a fastener aperture 64. A threaded fastener (not shown) was threaded through the fastener aperture 64 and used as a set screw to secure the frame member 14 to the bumper. Alternatively, the fastener aperture 64 can be disposed in the back side 42 of the body portion 40 of the unitary frame 14 for receiving a set screw. Fastener apertures 64 can be disposed on both the downwardly extending leg 62 and the back side 42 of the body portion 40 for passing threaded fasteners secure the device 10 to a bumper.

Other attachment means to bumpers are known to and practicable by the ordinary skilled artisan in accomplishing the present shoe cleaner device 10. For example, the unitary frame member of FIG. 2A is intended to be tied to a bumper 80 as illustrated in FIG. 3. As exemplified in the figure, the sport shoe cleaning device 10 is attached to the bumper 80 utilizing attachment means comprising strap tie apertures 70 for passing strap ties 72 (partially shown) closely around both the frame member 14 and the bumper 80 together to attach the frame member 14 to the bumper 80. Strap ties 72 useful for this purpose are known in the art and are commercially available. Alternatively, a tie means 72 can be disposed to pass from a tie aperture 70 on the appendage portion 60 (see FIG. 3), around the bumper 80 and to a tie aperture 70 on the body portion 40 of the frame member 14 to removably attach the device 10 to the bumper 80.

Sturdier, less-bendable flat stock (e.g., steel plate (e.g., {fraction (3/16)} in.)) may be readily utilized to construct the present brush mount 10 a. As illustrated by the preferred embodiment shown in FIGS. 4A to 4C. In this embodiment, the appendage portion 60 has a top plate section 104 that engages the top surface 84 of a vehicle bumper 80 (see FIG. 3). As shown in FIGS. 4A and 4B, the top plate 104 has a leading edge 106 and a trailing edge 108 which are substantially in parallel with each other and with the section of bumper 80 to be engaged. In the preferred embodiment illustrated, a flange 110 extends substantially perpendicularly in a downward direction (when the device 10 a is mounted the vehicle bumper 80) from the leading edge 106 of the top plate 104 to further engage the brush mount 10 a with the bumper 80. As shown in FIG. 4C, one or more fastener apertures 64 are disposed on the flange 110 of the brush mount 10 a. The fastener apertures may be threaded or not, but are used as known to one of skill in the art to pass a fastener through the flange 110 to secure the brush mount 10 a to a bumper 80. However, the flange is optional, and the top plate 104 itself may be provided with fastener apertures (not shown) with which to affix the top plate 104 directly to the top surface 84 of the bumper 80. One of ordinary skill in the art, in view of the disclosure and figures herein knows how to select which configuration of the top plate 104 to practice and how select appropriate fastening means with which to affix it to the bumper 80.

The body portion 120 of the brush mount 10 a is integral to and extends away from the trailing edge 108 of the top plate 104. The body portion 120 extends away from the top plate 104 at a downward angle of about 30 to 60 degrees relative to the plane of the top plate 104. The top plate is substantially horizontal when the device 10 a is mounted on a vehicle bumper 80 and has a top plate width Bw sufficient to engage the bumper top surface 84. Preferably, the body portion 120 extends away from the trailing edge 108 of the top plate 104 the full length Br of a brush or scraper mounted on the device 10 a, as illustrated in FIG. 4B. Alternatively, the body portion 120 may extend away from the trailing edge 108 of the top plate 104 only part of the length Br of a brush or scraper mounted on the device 10 a, as illustrated by the dashed line in FIG. 4A.

As shown in FIG. 5, the brush mount 10 a may include a stop means 130 which provides a vertical surface against which a surface of the bumper 80 is pressed or clamped, e.g., by a set screw (not shown) passed through a fastener aperture 64 on the flange plate 110. Alternatively, a set screw could be passed through a fastener aperture 64 in the stop means (see FIG. 6). The stop 130 can be a separate bracket (e.g., a section of angle stock) tacked welded in position as exemplified by the stop 130 in FIG. 5. Alternatively, the stop 130 can be partially cut from or stamped through the flat stock of the brush mount 10 a, then bent and tack welded as shown in FIG. 6. Also, if the brush mount 10 a is molded or cast, the stop means 130 can be integrated into the casting as shown in FIG. 7, or extruded from an endless mold having the cross-sectional configuration of FIG. 5.
